# never committed. A C++ consumer already needs a toolchain, so committing
# generated C++ would only create a second copy of the schema that can rot.
#
# gRPC C++ is optional here on purpose. The conformance test only needs message
# types, so the schema can be verified on a machine that has protobuf but not
# the gRPC C++ stack. When gRPC *is* found, the service stubs are generated too
# and exported as `shard_runtime_grpc` for the worker (DGR-008) to link.
# Protobuf and gRPC C++ are required together so message and service bindings are
# generated by one exact toolchain. The ignored bootstrap prefix supplies both.
#
# Build:
# cmake -S packages/node/native -B build/native -DCMAKE_PREFIX_PATH=<protobuf-install>
